SAFETY STEAM REGULATOR Application filed August 16, 1930. Serial No.475,827.

The present invention relates to steam reg ulating devices and moreparticularly to a safety regulator for interposition in a fuel supplyline.

An object of this invention is to provide a device of this characterwhich is particularly adapted to be interposed in a gas supply line andwhich is so constructed as to maintain a continuous flow of gas to theburner, the flow of gas being dependent upon the pressure of steam inthe boiler.

Another object of this invention is to provide an adjustable regulatorof this character which may be adjusted so as to maintain the desiredpressure of steam in the boiler, the

pressure of steam being dependent upon the quantity of fuel passingthrough the regulated supply line.

The above and various other objects and advantages of this inventionwill in part be described in and in part be understood from thefollowing detailed description of the present preferred embodiment, thesame being illustrated in the accompanying drawings wherein Figure 1 isa vertical sectional view partly in detail of a device constructedaccording to the preferred embodiment of this invention; and V Figure 2is a detail top plan view of the valve plate mounted within the device.

Referring to the drawings wherein like numerals of reference designatecorresponding parts throughout the several views, the

' numeral 10 designates generally a casing or housing comprising anupper member 11 and a lower member 12, the upper member 11 comprisingthe inlet chamber which is provided with an inlet port 13, and the lowermember 12 comprises an outlet chamber which is provided with an outletport 1 1. The inlet port 13 may be connected to one side of a fuelsupply line and preferably a gas line, and the outlet port 14: may beconnected to a burner of any desired type which is positioned in aboiler for generating steam, hot water, or the like.

A disc-like plate 15 is interposed between the upper and lower chambers11 and 12 respectively and is provided with a threaded axial aperture 16in which a valve seat 17 is positioned. The plate 15 may be securedbetween the upper and lower chambers 11 and 12 respectively by means ofbolts, screws or the like, 18. The lower end of the lower chamber 12 ispreferably restricted as at 19, and a plate 20 which is provided with anaxial pipe connection 21' is secured to the restricted lower end portionof the outlet chamber 12. An annulus 22 is interposed between the plate20 and the lower end of the chamber 12, the annulus 22 comprising aspacing ring or member, and an expansible or resilient diaphragm 23 isinterposed between the upper end of the spacing ring 22 and the lowerend of the outlet chamber 12, the diaphragm 23 and the plate 20providing a steam chamber in which steam from the boiler is adapted tobe positioned.

The plate 20, together with the annulus 22 and the diaphragm 23, may besecured to the outlet chamber 12 by means of bolts 24 or the like and,if desired, suitable packing members may be interposed between the plate20, the ring 22, and the diaphragm 23 so as to pre vent the steam withinthe steam chamber 25 from passing upwardly into the outlet fuel chamber12. valve member 26 is positioned on the diaphragm 23 and mounted withinthe outlet chamber 12, the valve 26 having a tapering upper end portionwhich is adapted to seat on the valve seat 17 The valve stem 27 extendsupwardly from the valve 26 and protrudes outwardly of the upper or inletchamber 11, and a threaded sleeve 28 is mounted axially of the upperchamber 11 and is positioned about the valve stem 27.

A spring 29 is mounted about the valve stem 27 within the upper chamber11, and one end of the spring 29 bears against a transversely disposedpin 30 which is mounted in the valve stem 27 and the opposite endengages against the lower end of the adjustable sleeve 28 so that whenthe sleeve-28 is moved longitudinally of the valve stem 27, the tensionof the spring 29 is correspondingly increased or decreased.

A washer 31 is interposed between the lower end of the spring 29 and thepin 30 and, in like manner, a second washer 32 is interposed between theupper end of the spring 29 and the lower end of the adjustable sleeve28. A look nut 33 is threadably positioned on the sleeve 28 so as tolock the sleeve in adjusted position. A packing gland 3 is positionedabout the valve stem 27 and is threadably mounted in the adjustablesleeve 28.

In the operation of this regulator, the in let port 13 may be connectedto the desired fuel line which maybe either agas line-or a fluid fuelline and the outlet'port 14: connected by suitable pipe connections tothe burner mounted in the boiler. connection 21 may be connected bysuitable pipe line to the steam boiler and the tension ofthe spring 29adjusted by means of the adjustable sleeve 28 so as to normally maintainthe valve 26 in open position. \Vhen a suitable pressure of steam hasbeen generated in the boiler, the steam will force the diaphragm 28upwardly and coactively move the valve 26 upwardly against the tensionof the spring 29 and thereby either close entirely or partially closethe valve opening so as to control the amount of fuel passing from theupper or inlet chamber to the lower oroutlet chamber and into theburner.

It will be obvious from the foregoing that a relatively simple regulatorhas been designed which may be mounted at any point in a fuel supplyline and which. will maintain the desired steam pressure in the boilerat all times. lVhile the regulator-herein disclosed has beenparticularly devised for use in connection with a gas fuel, I do notwish to be limited to this-construction as, if desired, the regulatorherein disclosed may be used with a liquid fuel supply line.

It is, of course, understood thatvarious changes and modifications maybe made in the details of construction and design of the abovespecifically described embodiment of this invention without departingfrom the spirit thereof, such changes and modifications beingrestrictedonly by the scope of the following claim:

What is claimed is A steam regulator comprising a casing including twomembers having abutting end portions, an outstanding flange carried byeach abutting end, securing means extending through the flanges, a rigidplate interposed between the flanges for dividing the casing into twocompartments and having an opening therethrough, one of saidcompartments having an intake port and the other having an outlet port,a valve member for closing the opening in said plate, resilient meansfor constantly urging said valve into open position, one of said membershaving a reduced flanged end, a flanged member engaging said reducedend, means engaging the flanges of said reduced end and said flangedmember for securing the flanged member to the reduced end, a diaphragminterposed between The steamsignature.
